FIELD OF THE INVENTION

The present invention relates generally to novel arylpropionamide, arylacrylamide, arylpropynamide, or arylmethylurea compounds, and analogues thereof, which are useful as selective inhibitors of serine protease enzymes of the coagulation cascade and/or contact activation system; for example thrombin, factor XIa, factor Xa, factor IXa and/or factor VIIa, and/or plasma kallikrein. In particular, it relates to compounds that are selective factor XIa inhibitors or dual inhibitors of fXIa and plasma kallikrein. This invention also relates to pharmaceutical compositions comprising these compounds and methods of using the same.

BACKGROUND OF THE INVENTION

Factor XIa is a plasma serine protease involved in the regulation of blood coagulation. While blood coagulation is essential to the regulation of an organism's hemostasis, it is also involved in many pathological conditions. In thrombosis, a blood clot, or thrombus, may form and obstruct circulation locally, causing ischemia and organ damage. Alternatively, in a process known as embolism, the clot may dislodge and subsequently become trapped in a distal vessel, where it again causes ischemia and organ damage. Diseases arising from pathological thrombus formation are collectively referred to as thrombotic or thromboembolic disorders and include acute coronary syndrome, unstable angina, myocardial infarction, thrombosis in the cavity of the heart, ischemic stroke, deep vein thrombosis, peripheral occlusive arterial disease, transient ischemic attack, and pulmonary embolism. In addition, thrombosis occurs on artificial surfaces in contact with blood, including catheters and artificial heart valves. Therefore, drugs that inhibit blood coagulation, or anticoagulants, are “pivotal agents for prevention and treatment of thromboembolic disorders” (Hirsh, J. et al. Blood 2005, 105, 453-463). Thromboembolic disorders are the largest cause of mortality and disability in the industrialized world.

Blood coagulation is initiated in vivo by the binding of tissue factor (TF) to Factor VII (FVII) to generate Factor VIIa (FVIIa). The resulting TF:FVIIa complex activates Factor IX (FIX) and Factor X (FX) which leads to the production of Factor Xa (FXa). The FXa that is generated catalyzes the transformation of prothrombin into small amounts of thrombin before this pathway is shut down by tissue factor pathway inhibitor (TFPI). The process of coagulation is then further propagated via the feedback activation of Factors V, VIII and XI by catalytic amounts of thrombin. (Walsh, P. N. Thromb. Haemostasis. 1999, 82, 234-242.) The resulting burst of thrombin coverts fibrinogen to fibrin, which polymerizes to form the structural framework of a blood clot, and activates platelets, which are a key cellular component of coagulation (Hoffman, M. Blood Reviews 2003, 17, S1-S5). Factor XIa plays a key role in propagating this amplification loop and is thus an attractive target for anti-thrombotic therapy.

An alternative way of initiation of coagulation is operative when blood is exposed to artificial surfaces (e.g., during hemodialysis, ‘on-pump’ cardiovascular surgery, vessel grafts, bacterial sepsis), on cell surfaces, cellular receptors, and extracellular matrices. This process is also termed contact activation. Surface absorption of factor XII leads to a conformational change in the factor XII molecule, thereby facilitating activation to proteolytic active factor XII molecules (factor XIIa and factor XIIf). Factor XIIa (or XIIf) has a number of target proteins, including plasma prekallikrein and factor XI. Active plasma kallikrein further activates factor XII, leading to an amplification of contact activation. Alternatively, the serine protease prolylcarboxylpeptidase can activate plasma kallikrein complexed with high molecular weight kininogen in a multiprotein complex formed on the surface of cells and matrices (Shariat-Madar et al. Blood 2006, 108, 192-199). Contact activation is a surface mediated process responsible in part for the regulation of thrombosis and inflammation, and is mediated, at least in part, by fibrinolytic-, complement-, kininogen/kinin-, and other humoral and cellular pathways (for review, Coleman, R. Contact Activation Pathway, pages 103-122 in Hemostasis and Thrombosis, Lippincott Williams & Wilkins 2001; Schmaier A. H. Contact Activation, pages 105-128 in Thrombosis and Hemorrhage, 1998). The biological relevance of the contact activation system for thromboembolic diseases is supported by the phenotype of factor XII deficient mice. More specifically, factor XII deficient mice were protected from thrombotic vascular occlusion in several thrombosis models as well as stroke models and the phenotype of the XII deficient mice was identical to XI deficient mice (Renne et al. J. Exp. Medicine 2005, 202, 271-281; Kleinschmitz et al. J. Exp.l Medicine, 2006, 203, 513-518). The fact that factor XI is down-stream from factor XIIa, combined with the identical phenotype of the XII and XI deficient mice suggest that the contact activation system could play a major role in factor XI activation in vivo.

Factor XI is a zymogen of a trypsin-like serine protease and is present in plasma at a relatively low concentration. Proteolytic activation at an internal R369-I370 bond yields a heavy chain (369 amino acids) and a light chain (238 amino acids). The latter contains a typical trypsin-like catalytic triad (H413, D464, and S557). Activation of factor XI by thrombin is believed to occur on negatively charged surfaces, most likely on the surface of activated platelets. Platelets contain high affinity (0.8 nM) specific sites (130-500/platelet) for activated factor XI. After activation, factor XIa remains surface bound and recognizes factor IX as its normal macromolecular substrate. (Galiani, D. Trends Cardiovasc. Med. 2000, 10, 198-204.)

In addition to the feedback activation mechanisms described above, thrombin activates thrombin activated fibrinolysis inhibitor (TAFI), a plasma carboxypeptidase that cleaves C-terminal lysine and arginine residues on fibrin, reducing the ability of fibrin to enhance tissue-type plasminogen activator (tPA) dependent plasminogen activation. In the presence of antibodies to FXIa, clot lysis can occur more rapidly independent of plasma TAFI concentration. (Bouma, B. N. et al. Thromb. Res. 2001, 101, 329-354.) Thus, inhibitors of factor XIa are expected to be anticoagulant and profibrinolytic.

Further evidence for the anti-thromboembolic effects of targeting factor XI is derived from mice deficient in factor XI. It has been demonstrated that complete fXI deficiency protected mice from ferric chloride (FeCl₃)-induced carotid artery thrombosis (Rosen et al. Thromb Haemost 2002, 87, 774-77; Wang et al., J Thromb Haemost 2005, 3, 695-702). Also, factor XI deficiency rescues the perinatal lethal phenotype of complete protein C deficiency (Chan et al., Amer. J. Pathology 2001, 158, 469-479). Furthermore, baboon cross-reactive, function blocking antibodies to human factor XI protect against baboon arterial—venous shunt thrombosis (Gruber et al., Blood 2003, 102, 953-955). Evidence for an antithrombotic effect of small molecule inhibitors of factor XIa is also disclosed in published U.S. Patent Application US20040180855A1. Taken together, these studies suggest that targeting factor XI will reduce the propensity for thrombotic and thromboembolic diseases.

Genetic evidence indicates that factor XI is not required for normal homeostasis, implying a superior safety profile of the factor XI mechanism compared to competing antithrombotic mechanisms. In contrast to hemophilia A (factor VIII deficiency) or hemophilia B (factor IX deficiency), mutations of the factor XI gene causing factor XI deficiency (hemophilia C) result in only a mild to moderate bleeding diathesis characterized primarily by postoperative or posttraumatic, but rarely spontaneous hemorrhage. Postoperative bleeding occurs mostly in tissue with high concentrations of endogenous fibrinolytic activity (e.g. oral cavity, and urogenital system). The majority of the cases are fortuitously identified by preoperative prolongation of APTT (intrinsic system) without any prior bleeding history.

The increased safety of inhibition of XIa as an anticoagulation therapy is further supported by the fact that Factor XI knock-out mice, which have no detectable factor XI protein, undergo normal development, and have a normal life span. No evidence for spontaneous bleeding has been noted. The APTT (intrinsic system) is prolonged in a gene dose-dependent fashion. Interestingly, even after severe stimulation of the coagulation system (tail transection), the bleeding time is not significantly prolonged compared to wild-type and heterozygous litter mates. (Gailani, D. Frontiers in Bioscience 2001, 6, 201-207; Gailani, D. et al. Blood Coagulation and Fibrinolysis 1997, 8, 134-144.) Taken together, these observations suggest that high levels of inhibition of factor XIa should be well tolerated. This is in contrast to gene targeting experiments with other coagulation factors.

In vivo activation of factor XI can be determined by complex formation with either C1 inhibitor or alpha 1 antitrypsin. In a study of 50 patients with acute myocardial infarction (AMI), approximately 25% of the patients had values above the upper normal range of the complex ELISA. This study can be viewed as evidence that at least in a subpopulation of patients with AMI, factor XI activation contributes to thrombin formation (Minnema, M. C. et al. Arterioscler. Thromb. Vasc. Biol. 2000, 20, 2489-2493). A second study establishes a positive correlation between the extent of coronary arteriosclerosis and factor XIa in complex with alpha 1 antitrypsin (Murakami, T. et al. Arterioscler Thromb Vasc Biol 1995, 15, 1107-1113.). In another study, Factor XI levels above the 90^(th) percentile in patients were associated with a 2.2-fold increased risk for venous thrombosis (Meijers, J. C. M. et al. N. Engl. J. Med. 2000, 342, 696-701.).

Plasma kallikrein is a zymogen of a trypsin-like serine protease and is present in plasma at 35 to 50 μg/mL. The gene structure is similar to that of factor XI. Overall, the amino acid sequence of plasma kallikrein has 58% homology to factor XI. Proteolytic activation by factor XIIa at an internal I 389-R390 bond yields a heavy chain (371 amino acids) and a light chain (248 amino acids). The active site of plasma kallikrein is contained in the light chain. The light chain of plasma kallikrein reacts with protease inhibitors, including alpha 2 macroglobulin and C1-inhibitor. Interestingly, heparin significantly accelerates the inhibition of plasma kallikrein by antithrombin III in the presence of high molecular weight kininogen (HMWK). In blood, the majority of plasma kallikrein circulates in complex with HMWK. Plasma kallikrein cleaves HMWK to liberate bradykinin. Bradykinin release results in increase of vascular permeability and vasodilation (for review, Coleman, R. Contact Activation Pathway, pages 103-122 in Hemostasis and Thrombosis, Lippincott Williams & Wilkins 2001; Schmaier A. H. Contact Activation, pages 105-128 in Thrombosis and Hemorrhage, 1998).

Proteins or peptides that reportedly inhibit Factor XIa are disclosed in WO 01/27079. There are advantages in using small organic compounds, however, in preparing pharmaceuticals, e.g., small compounds generally have better oral bioavailability and compatibility in making formulations to aid in delivery of the drug as compared with large proteins or peptides. Small molecule inhibitors of Factor XIa are disclosed in U.S. Patent Application Publications, e.g., US20040235847A1, US20040220206A1, US20050228000A1, US20060009455A1, and US20050282805A1.

In addition, it is also desirable to find new compounds with improved pharmacological characteristics compared with known serine protease inhibitors. For example, it is preferred to find new compounds with improved factor XIa inhibitory activity and selectivity for factor XIa versus other serine proteases. Also, it is preferred to find new compounds with improved plasma kallikrein inhibitory activity and selectivity for plasma kallikrein versus other serine proteases. It is also desirable and preferable to find compounds with advantageous and improved characteristics in one or more of the following categories, which are given as examples and are not intended to be limiting: (a) pharmacokinetic properties, including oral bioavailability; (b) pharmaceutical properties; (c) dosage requirements; (d) factors which decrease blood concentration peak-to-trough characteristics; (e) factors that increase the concentration of active drug at the receptor; (f) factors that decrease the liability for clinical drug-drug interactions; (g) factors that decrease the potential for adverse side-effects; and (h) factors that improve manufacturing costs or feasibility.

Also included are fused ring and spiro compounds containing, for example, the above heterocycles.

As used herein, the term “aromatic heterocyclic group” or “heteroaryl” is intended to mean a stable monocyclic and polycyclic aromatic hydrocarbons that include at least one heteroatom ring member such as sulfur, oxygen, or nitrogen. Heteroaryl groups include, without limitation, pyridyl, pyrimidinyl, pyrazinyl, pyridazinyl, triazinyl, furyl, quinolyl, isoquinolyl, thienyl, imidazolyl, thiazolyl, indolyl, pyrroyl, oxazolyl, benzofuryl, benzothienyl, benzthiazolyl, isoxazolyl, pyrazolyl, triazolyl, tetrazolyl, indazolyl, 1,2,4-thiadiazolyl, isothiazolyl, purinyl, carbazolyl, benzimidazolyl, indolinyl, benzodioxolanyl, benzodioxane, and the like. Heteroaryl groups can be substituted or unsubstituted. The nitrogen atom may be substituted or unsubstituted (i.e., N or NR wherein R is H or another substituent, if defined). The nitrogen and sulfur heteroatoms may optionally be oxidized (i.e., N→O and S(O)_(p)). It is to be noted that total number of S and O atoms in the aromatic heterocycle is not more than 1. Bridged rings are also included in the definition of heterocycle. A bridged ring occurs when one or more atoms (i.e., C, O, N, or S) link two non-adjacent carbon or nitrogen atoms. Preferred bridges include, but are not limited to, one carbon atom, two carbon atoms, one nitrogen atom, two nitrogen atoms, and a carbon-nitrogen group. It is noted that a bridge always converts a monocyclic ring into a tricyclic ring. When a ring is bridged, the substituents recited for the ring may also be present on the bridge.

The term “counterion” is used to represent a small, negatively charged species such as chloride, bromide, hydroxide, acetate, sulfate, and the like.

As referred to herein, the term “substituted” means that one or more hydrogen atoms is replaced with a non-hydrogen group, provided that normal valencies are maintained and that the substitution results in a stable compound. When a substituent is keto (i.e., ═O), then 2 hydrogens on the atom are replaced. Keto substituents are not present on aromatic moieties. When a ring system (e.g., carbocyclic or heterocyclic) is said to be substituted with a carbonyl group or a double bond, it is intended that the carbonyl group or double bond be part (i.e., within) of the ring. Ring double bonds, as used herein, are double bonds that are formed between two adjacent ring atoms (e.g., C═C, C═N, or N═N).

In cases wherein there are nitrogen atoms (e.g., amines) on compounds of the present invention, these may be converted to N-oxides by treatment with an oxidizing agent (e.g., mCPBA and/or hydrogen peroxides) to afford other compounds of this invention. Thus, shown and claimed nitrogen atoms are considered to cover both the shown nitrogen and its N-oxide (N→O) derivative. In cases wherein there are quaternary carbon atoms on compounds of the present invention, these can be replaced by silicon atoms, provided they do not form Si—N or Si—O bond.

When any variable occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-3 R^(3a), then said group may optionally be substituted with up to three R^(3a) groups and R^(3a) at each occurrence is selected independently from the definition of R^(3a). Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic groups such as amines; and alkali or organic salts of acidic groups such as carboxylic acids. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, and nitric; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, and isethionic, and the like.

The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 18th ed., Mack Publishing Company, Easton, Pa., 1990, the disclosure of which is hereby incorporated by reference.

In addition, compounds of formula I may have prodrug forms. Any compound that will be converted in vivo to provide the bioactive agent (i.e., a compound of formula I) is a prodrug within the scope and spirit of the invention. Various forms of prodrugs are well known in the art. For examples of such prodrug derivatives, see:

(Academic Press, 1985);     -   b) A Textbook of Drug Design and Development, edited by         Krosgaard-Larsen and H. Bundgaard, Chapter 5, “Design and         Application of Prodrugs,” by H. Bundgaard, at pp. 113-191         (1991);     -   c) H. Bundgaard, Advanced Drug Delivery Reviews, Vol. 8, p. 1-38         (1992);     -   d) H.

Compounds containing a carboxy group can form physiologically hydrolyzable esters which serve as prodrugs by being hydrolyzed in the body to yield formula I compounds per se. Such prodrugs are preferably administered orally since hydrolysis in many instances occurs principally under the influence of the digestive enzymes. Parenteral administration may be used where the ester per se is active, or in those instances where hydrolysis occurs in the blood. Examples of physiologically hydrolyzable esters of compounds of formula I include C₁₋₆alkyl, C₁₋₆alkylbenzyl, 4-methoxybenzyl, indanyl, phthalyl, methoxymethyl, C₁₋₆ alkanoyloxy-C₁₋₆alkyl, e.g. acetoxymethyl, pivaloyloxymethyl or propionyloxymethyl, C₁₋₆alkoxycarbonyloxy-C₁₋₆alkyl, e.g. methoxycarbonyl-oxymethyl or ethoxycarbonyloxymethyl, glycyloxymethyl, phenylglycyloxymethyl, (5-methyl-2-oxo-1,3-dioxolen-4-yl)-methyl and other well known physiologically hydrolyzable esters used, for example, in the penicillin and cephalosporin arts. Such esters may be prepared by conventional techniques known in the art.

Preparation of Prodrugs is Well Known in the Art and Described in, for example, Medicinal Chemistry: Principles and Practice, ed. F. D. King, The Royal Society of Chemistry, Cambridge, UK, 1994, which is incorporated herein by reference in its entirety.

Isotopically labeled compounds of the present invention, i.e., wherein one or more of the atoms described are replaced by an isotope of that atom (e.g., C replaced by ¹³C or by ¹⁴C; and isotopes of hydrogen include tritium and deuterium), are also provided herein. Such compounds have a variety of potential uses, e.g., as standards and reagents in determining the ability of a potential pharmaceutical to bind to target proteins or receptors, or for imaging compounds of this invention bound to biological receptors in vivo or in vitro.

Compounds of the present invention are, subsequent to their preparation, preferably isolated and purified to obtain a composition containing an amount by weight equal to or greater than 98%, preferably 99%, compound of the present invention (“substantially pure”), which is then used or formulated as described herein. Such “substantially pure” compounds are also contemplated herein as part of the present invention.

“Stable compound” and “stable structure” are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent. It is preferred that compounds of the present invention do not contain a N-halo, S(O)₂H, or S(O)H group.

The term “solvate” means a physical association of a compound of this invention with one or more solvent molecules, whether organic or inorganic. This physical association includes hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. “Solvate” encompasses both solution-phase and isolable solvates. Exemplary solvates include hydrates, ethanolates, methanolates, isopropanolates and the like. Methods of salvation are generally known in the art.

As used herein, the term “patient” encompasses all mammalian species.

As used herein, “treating” or “treatment” cover the treatment of a disease-state in a mammal, particularly in a human, and include: (a) preventing the disease-state from occurring in a mammal, in particular, when such mammal is predisposed to the disease-state but has not yet been diagnosed as having it; (b) inhibiting the disease-state, i.e., arresting it development; and/or (c) relieving the disease-state, i.e., causing regression of the disease state.

“Therapeutically effective amount” is intended to include an amount of a compound of the present invention that is effective when administered alone or in combination to inhibit factor XIa and/or plasma kallikrein or to treat the disorders listed herein. When applied to a combination, the term refers to combined amounts of the active ingredients that result in the therapeutic effect, whether administered in combination, serially or simultaneously. The combination of compounds is preferably a synergistic combination. Synergy, as described, for example, by Chou and Talalay, Adv. Enzyme Regul. 1984, 22:27-55, occurs when the effect (in this case, prevention of thrombosis) of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at sub-optimal concentrations of the compounds. Synergy can be in terms of lower cytotoxicity, increased antithrombotic and/or anti-inflammatory effect, or some other beneficial effect of the combination compared with the individual components.

The term “pharmaceutical composition” means a composition comprising a compound of the invention in combination with at least one additional pharmaceutically acceptable carrier. A “pharmaceutically acceptable carrier” refers to media generally accepted in the art for the delivery of biologically active agents to animals, in particular, mammals, including, i.e., adjuvant, excipient or vehicle, such as diluents, preserving agents, fillers, flow regulating agents, disintegrating agents, wetting agents, emulsifying agents, suspending agents, sweetening agents, flavoring agents, perfuming agents, antibacterial agents, antifungal agents, lubricating agents and dispensing agents, depending on the nature of the mode of administration and dosage forms. Pharmaceutically acceptable carriers are formulated according to a number of factors well within the purview of those of ordinary skill in the art. These include, without limitation: the type and nature of the active agent being formulated; the subject to which the agent-containing composition is to be administered; the intended route of administration of the composition; and the therapeutic indication being targeted. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semi-solid dosage forms. Such carriers can include a number of different ingredients and additives in addition to the active agent, such additional ingredients being included in the formulation for a variety of reasons, e.g., stabilization of the active agent, binders, etc., well known to those of ordinary skill in the art. Descriptions of suitable pharmaceutically acceptable carriers, and factors involved in their selection, are found in a variety of readily available sources such as, for example, Remington's Pharmaceutical Sciences, 18th ed., 1990, which is incorporated herein by reference in its entirety.

Synthesis

The compounds of the present invention can be prepared in a number of ways known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or by variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention. Also, in the description of the synthetic methods described below, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and workup procedures, are chosen to be the conditions standard for that reaction, which should be readily recognized by one skilled in the art. It is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the molecule must be compatible with the reagents and reactions proposed. Such restrictions to the substituents that are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternate methods must then be used.

It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts (Protective Groups In Organic Synthesis, Wiley-Interscience, 3^(rd) Edition, 1999).

All references cited herein are hereby incorporated in their entirety herein by reference.

Compounds of this invention wherein L is —CH₂NHC(O)NH— can be prepared as outlined in Scheme 1. Condensation of an appropriately functionalized amine intermediate 1a with a suitably substituted benzylisocyanate 1b in a solvent such as tetrahydrofuran or methylene chloride in the presence of a base such as triethylamine, diisopropylethylamine or potassium carbonate provides ureas of formula 1c. Alternatively, ureas of formula 1c of this invention can be prepared by condensation of an amine intermediate 1a with carbonyl diimidazole in a solvent such as tetrahydrofuran or N,N-dimethylformamide followed by treatment in situ with an suitably substituted benzyl amine 1d. Urea linked compounds of this invention of formula 1c can also be prepared by condensation of amine intermediate 1a with p-nitrophenylchloroformate in the presence of a suitable base such as triethylamine, followed by treatment of the resulting p-nitrophenylcarbamate with an appropriate substituted amine 1d.

Isocyanates of formula 1b used in Scheme 1 above are either commercially available or can be readily prepared from the corresponding amines 1d by treatment with phosgene or by various other methods known in the art (see for example, H. Eckert & B. Forster, Angew. Chem. Int. Ed. 1987, 26, 894; H. Knolker & T. Braxmeier, Synlett, 1997, 925; S. Porwanski et al. Tetrahedron Lett. 2004, 45, 5027). Amines of formula 1d are also available commercially or can be prepared by those knowledgeable in the art from a variety of easily accessible starting materials such as nitrites, aldehydes, alcohols, halides, acids and esters by methods including, but not limited to those outlined in Scheme 2.

Compounds of this invention wherein L is —NHNHC(O)NH— of formula 3c can be synthesized similarly as outlined in Scheme 3 by treatment of a suitably functionalized amine intermediate 1a with p-nitrochloroformate as described above followed by treatment of the resulting p-nitrophenylcarbamate 3a with a suitably substituted hydrazine of formula 3b.

Hydrazine reagents of formula 3b used to prepare compounds of this invention in Scheme 3 are commercially available or can be prepared by those knowledgeable in the art of organic synthesis by other methods. For example, when A is an aryl or heteroaryl group, the requisite hydrazine reagent is readily available via diazotization of a starting aryl or heteroarylamine 4a followed by reduction of the resulting diazonium salt with tin chloride to the corresponding arylhydrazine 4b as illustrated in Scheme 4.

Compounds of this invention wherein L is —(CH₂)₂CONH—, —CH═CHCONH—, —C≡CCONH—, —OCH₂CONH—, or —SCH₂CONH—, can be obtained by the condensation of the amine intermediate 1a shown in Scheme 1 with appropriately substituted carboxylic acid chlorides, mixed carboxylic acid anhydrides or carboxylic acids using standard amide bond forming conditions known to one skilled in the art. Reagent combinations which may be employed for the coupling of amines of formula 1a with suitably substituted carboxylic acids include, but are not limited to: BOP-reagent and triethylamine, EDCI, HOBt, and N-methylmorpholine, or HATU and Hunig's base (DIPEA). Solvents suitable for this transformation include, but are not limited to tetrahydrofuran and dimethylformamide. Coupling of amines of formula 1a with suitably substituted carboxylic acid chlorides or mixed anhydrides can be carried out in solvents such as methylene chloride or tetrahydrofuran in the presence of a base such as triethylamine, N,N-dimethyaminopyridine (DMAP) or potassium carbonate. Suitably substituted carboxylic acids (A-(CH₂)₂CO₂H) 5a are either commercially available, or they can be prepared from the corresponding bromides, alcohols, aldehydes, or esters as shown in Scheme 5 using methods known to one skilled in the art.

Additional carboxylic acid intermediates of formulae 6a, 6b, 6c, and 6d useful for preparation of amide compounds of this invention can be prepared as outlined in Schemes 6 and 6A.

The syntheses of amines of formula 1a useful for the synthesis of compounds of this invention as outlined in the above schemes, where M is a substituted imidazole of formula IIa, is described in US patent application, 2005/282805 published Dec. 22, 2005, which is incorporated in its entirety herein by reference. Additional amines of formula 1a where in M is a substituted pyridine or pyridone of formula IIb or IIc are prepared as described in PCT patent application WO2005/123680, published Dec. 29, 2005, which is incorporated in its entirety herein by reference. Other pyridine regioisomers of IIb, along with pyrimidine analogs, can be prepared according to U.S. Provisional Application No. 60/750,416, filed Dec. 14, 2005, which is incorporated in its entirety herein by reference.

The synthesis of some representative examples of compounds of this invention are depicted in Schemes 7-10A. Substitution of other N-protected amino acids in place of Boc-Phe or Boc-Asp(OBn)—OH in Schemes 7, and 8-10A below will provide additional compounds of this invention.

Alternately, imidazole compounds of this invention can be prepared by introduction of R³ groups via palladium-mediated coupling to an intermediate 4-bromo-5-chloroimidazole intermediate prepared as shown in Scheme 11. Alternate boronic acid or boronic ester coupling partners that are commercially available or readily synthesized by methods known to one skilled in the art may be employed in this palladium-mediated step to afford additional compounds of this invention.

Chiral amino acids useful for the synthesis of imidazole compounds of this invention are either commercially available or can be prepared by any of a number of methods known in the art. For example, as shown in Scheme 12, didehydroamino acid derivatives of formula 12c may be reduced to provide protected (s)-amino acids of formula 12d by hydrogenation in the presence of a chiral catalyst such as (S,S)-EtDuPhosRh(I) using a modified procedure of Burk (J. Am. Chem. Soc., 1991, 113, 8518). Didehydroamino acid derivatives of formula 12c can be prepared via several methods, such as for example, a Heck coupling between an aryl iodide, bromide, or tosylate of formula 12a and Boc didehydroalanine benzyl ester, using a modified procedure of Carlström, et al. (Synthesis, 1989, 414). Alternatively, protected didehydroaminoacids of formula 12c may be prepared by Horner-Emmons type condensation of an aldehyde of formula 12b with Boc-methyl-2-(dimethylphosphono)glycinate, using modifications of literature procedures (Wang, et al. Tetrahedron, 2002, 58, 3101). Protected amino acids of formula 12d may also be prepared by alkylation of methyl 2-(diphenylmethyleneamino)acetate with an appropriately substituted benzylbromide in the presence of a chiral cinchonidinium catalyst in a suitable solvent, such as methylene chloride, using a procedure similar to that described by O'Donnell, et al. (Tetrahedron, 1999, 55, 6347), followed by mild acidic workup and reprotection of the amino functionality with a Boc group according to methods known to one skilled in the art. Substitution of heteroaryl bromides or iodides for 12a, heteroaryl or alkyl aldehydes for 12b, and heteroarylalkyl or alkylbromides for 12c in Scheme 12 would lead to additional chiral amino acids useful for the synthesis of imidazole compounds of this invention. For example, optionally substituted pyrazole carbaldehydes may be used in place of benzaldehydes 12b to give compounds of this invention wherein R¹¹ is an optionally substituted pyrazolylmethyl group.

Methods for synthesis of a large variety of substituted pyridine and pyridone compounds useful as starting materials for the preparation of compounds of the present invention are well known in the art and have been extensively reviewed. (For examples of methods useful for the preparation of pyridine and pyridone starting materials see: Krohnke, F. Synthesis, 1976, 1.; Pyridine and Its Derivatives. In The Chemistry of Heterocyclic Compounds, Abramovitch, R. A., Ed.; John Wiley and Sons: New York, 1974; Vol 14; Supplemental 1-4.; Comprehensive Heterocyclic Chemistry, Vol. 2, Boulton, A. J. and McKillop, A, Eds. Pergamon Press, New York, 1984, pp 165-524; Comprehensive Heterocyclic Chemistry, Vol. 5, McKillop, A, Ed. Pergamon Press, New York, 1996, pp 1-300).

Representative pyridine compounds of this invention can be prepared as shown in Scheme 13. Suzuki coupling between an appropriately functionalized pyridine, such as 13a and an appropriately substituted aryl or heteroaryl boronic acid or ester 13b in the presence of a base such as anhydrous potassium carbonate in a solvent such as methanol or THF using a catalyst such as PXPd2 provides the biaryl compound. Using a modification of the procedure described by Schlosser (Schlosser, M. and Cottet, F. Eur. J. Org. Chem., 2002, 24, 4181-4184), the 2-chloropyridine derivative is treated with trimethylsilyl bromide in propionitrile at elevated temperature in a microwave to give the 2-bromopyridine derivative 13c. Metal-halogen exchange with n-butyllithium and quenching the intermediate anion with a suitable formyl source such as 1-formyl piperidine or DMF provides aldehyde 13d. Using a modification of the procedure described by Hart (Hart, D. J. et al. J. Org. Chem., 1983, 48(3), 289-294), in situ generation of N-trimethylsilylaldimines from 13d and lithium bis(trimethylsilyl)amide, followed by the addition of Grignard or alkyllithium reagents give after aqueous work up the primary amine 13e. Coupling between 13e and 1b or 1d, according to Scheme 1, gives 13f. Alternately, coupling between 13e and 3b, according to Scheme 3, gives 13g. Alternately, amide coupling between 13e and 5a, 6b, 6c, or 6d employing suitable coupling reagents, such as EDCI, HOBt, and base generates 13h, 13i, and 13n. (for alternative coupling reagents see: Han, S-Y; Kim, Y-A. Tetrahedron, 2004, 60, 2447). The pyridine N-oxide derivatives 13j-m and 13o can be prepared by oxidation of 13f-i and 13n with a suitable oxidant such as m-chloroperbenzoic acid in chloroform. Further manipulation of functional groups on A, R³, and R⁴ using methods known to one skilled in the art of organic synthesis will give additional compounds of the invention.

Alternately, the R³ moiety can be introduced via a Suzuki coupling strategy later in the synthesis as shown in Scheme 14. Compound 14c can be prepared in three steps according to a modified procedure described by Negi (Negi, S. et al. Synthesis, 1996, 991). Addition of Grignard or lithium reagents to a suitably substituted ester or Weinreb amide 14a yields ketone 14b. Condensation of 14b with hydroxylamine hydrochloride generates the oxime which can be reduced to the primary amine 14c with zinc dust and TFA. Boc protection of 14c gives 14d. Suzuki coupling between 4-chloropyridine 14d and an appropriately substituted aryl or heteroaryl boronic acid or ester 13b in the presence of a base such as anhydrous cesium carbonate, potassium fluoride, or potassium phosphate in a solvent, such as dioxane, dimethylsulfoxide, or dimethylformamide, using a catalyst such as tetrakis(triphenylphosphine)palladium(0), tris(dibenzylideneacetone)dipalladium(0) and tri-t-butylphosphonium tetrafluoroborate or Pd(dppf)₂Cl₂.CH₂Cl₂ complex provides the biaryl compound. Boc deprotection with TFA gives 13e. Coupling between 13e and 1b or 1d, according to Scheme 1, gives 13f. Alternately, coupling between 13e and 3b, according to Scheme 3, gives 13g. Alternately, amide coupling between 13e and 5a, 6b, 6c, or 6d employing suitable coupling reagents, such as EDCI, HOBt, and base generates 13h, 13i, and 13n. (for alternative coupling reagents see: Han, S-Y; Kim, Y-A. Tetrahedron, 2004, 60, 2447). The pyridine N-oxide derivatives 13j-m and 13o can be prepared by oxidation of 13f-i and 13n with a suitable oxidant such as m-chloroperbenzoic acid in chloroform. Further manipulation of functional groups on A, R³, and R⁴ using methods known to one skilled in the art of organic synthesis will give additional compounds of the invention.

In cases where suitably substituted boronic acids are not commercially available, a modification to this approach may be adopted wherein an aryl halide is subjected to a palladium mediated coupling with a diboron species such as bis(pinacolato) diboron to provide the corresponding 4,4,5,5-tetramethyl-[1,3,2]dioxaborolane intermediate using the method of Ishiyama, T. et al. (J. Org. Chem. 1995, 60(23), 7508-7510). Alternately, this same intermediate can be prepared by reaction of the intermediate halide with the corresponding dialkoxyhydroborane as described by Murata et al. (J. Org. Chem. 1997, 62(19), 6458-6459). The boron pinacolate intermediates can be used in place of boronic acids for coupling to the aryl/heteroaryl halides or triflates or the boron pinacolate intermediate can be converted to the boronic acids. Alternately, the corresponding boronic acids can be prepared by metal-halogen exchange of the aryl/heteroaryl halide, quenching with a trialkoxyborate reagent, and aqueous workup to provide the boronic acids (Miyaura, N.; Suzuki, A. Chem. Review, 1995, 95, 2457).

It is also realized that the scope of intermediate synthesis can be further extended outside the use of Suzuki methodology since the precursor aryl halides or triflates described above are also precursors for Stille, Negishi, Hiyama, and Kumada-type cross coupling methodologies (Tsuji, J. Transition Metal Reagents and Catalysts: Innovations in Organic Synthesis, John Wiley & Sons, 2000; Tsuji, J. Palladium Reagents and Catalysts: Innovations in Organic Synthesis, John Wiley & Sons, 1996.)

Representative pyridone compounds of this invention can be prepared as shown in Scheme 15. Compound 15d can be prepared in two steps according to a modified procedure described by Resmini (Resmini, M. et al., Tetrahedron Asymmetry, 2004, 15, 1847). A suitably substituted amino ester 15a can be converted to the corresponding β-ketophosphonate 15b by treatment with lithium dimethylmethylphosphonate. Horner-Wadsworth-Emmons reaction of 15b and a suitably substituted aldehyde 15c in the presence of base such as potassium carbonate in a solvent such as ethanol or tetrahydrofuran gives the α,β-unsaturated ketone 15d. Condensation of 15d with 1-(ethoxycarbonylmethyl)-pyridinium chloride or 1-(carbamoylmethyl)-pyridinium chloride in the presence of ammonium acetate in a solvent such as ethanol or glacial acetic acid generates the pyridone 15e. Boc deprotection with TFA gives 15f Coupling between 15f and 1b or 1d, according to Scheme 1, gives 15g. Alternately, coupling between 15f and 3b, according to Scheme 3, gives 15h. Alternately, amide coupling between 15f and 5a, 6b, 6c, or 6d employing suitable coupling reagents, such as EDCI, HOBt, and base generates 15i, 15j, or 15k. (for alternative coupling reagents see: Han, S-Y; Kim, Y-A. Tetrahedron, 2004, 60, 2447). Further manipulation of functional groups on A and R³ using methods known to one skilled in the art of organic synthesis will give additional compounds of the invention.

It should be recognized that additional deprotection steps and further functional group manipulations of compounds obtained via Schemes 1-15 above using methods known in the art will then provide additional compounds of this invention.

Filtration provided a yellow solid which was washed with diethyl ether, air-dried, then dried under vacuum to obtain 21.20 g of 95% pure product. The filtrate was concentrated to dryness and diethyl ether (500 mL) was added. Sonication yielded a fine suspension which was filtered to provide a yellow solid which was washed with diethyl ether, air-dried, then dried under vacuum to produce an additional 35.5 g of 50% pure product. To a cooled (0° C.) suspension of the latter material (35.5 g) in CH₂Cl₂ (500 mL) was added sat. NaHCO₃ (300 mL). The suspension was stirred vigorously to dissolve most of the solid.

Utility

The compounds of this invention are inhibitors of factor XIa and are useful as anticoagulants for the treatment or prevention of thromboembolic disorders in mammals (i.e., factor XIa-associated disorders). In general, a thromboembolic disorder is a circulatory disease caused by blood clots (i.e., diseases involving fibrin formation, platelet activation, and/or platelet aggregation). The term “thromboembolic disorders” as used herein includes arterial cardiovascular thromboembolic disorders, venous cardiovascular or cerebovascular thromboembolic disorders, and thromboembolic disorders in the chambers of the heart or in the peripheral circulation. The term “thromboembolic disorders” as used herein also includes specific disorders selected from, but not limited to, unstable angina or other acute coronary syndromes, atrial fibrillation, first or recurrent myocardial infarction, ischemic sudden death, transient ischemic attack, stroke, atherosclerosis, peripheral occlusive arterial disease, venous thrombosis, deep vein thrombosis, thrombophlebitis, arterial embolism, coronary arterial thrombosis, cerebral arterial thrombosis, cerebral embolism, kidney embolism, pulmonary embolism, and thrombosis resulting from medical implants, devices, or procedures in which blood is exposed to an artificial surface that promotes thrombosis. The medical implants or devices include, but are not limited to: prosthetic valves, artificial valves, indwelling catheters, stents, blood oxygenators, shunts, vascular access ports, ventricular assist devices and artificial hearts or heart chambers, and vessel grafts. The procedures include, but are not limited to: cardiopulmonary bypass, percutaneous coronary intervention, and hemodialysis.

It is noted that thrombosis includes vessel occlusion (e.g., after a bypass) and reocclusion (e.g., during or after percutaneous transluminal coronary angioplasty). The thromboembolic disorders may result from conditions including but not limited to atherosclerosis, surgery or surgical complications, prolonged immobilization, arterial fibrillation, congenital thrombophilia, cancer, diabetes, effects of medications or hormones, and complications of pregnancy. The anticoagulant effect of compounds of the present invention is believed to be due to inhibition of serine proteases involved in the coagulation cascade and/or contact activation system, more specifically, inhibition of the coagulation factors: factor XIa, factor VIIa, factor IXa, factor Xa, plasma kallikrein or thrombin.

The term “thrombosis”, as used herein, refers to formation or presence of a thrombus (pl. thrombi); clotting within a blood vessel which may cause ischemia or infarction of tissues supplied by the vessel. The term “embolism”, as used herein, refers to sudden blocking of an artery by a clot or foreign material which has been brought to its site of lodgment by the blood current. The term “thromboembolism”, as used herein, refers to obstruction of a blood vessel with thrombotic material carried by the blood stream from the site of origin to plug another vessel. The term “stroke”, as used herein, refers to embolic stroke or atherothrombotic stroke arising from occlusive thrombosis in the carotid communis, carotid interna, or intracerebral arteries.

The compounds of this invention also are inhibitors of plasma kallikrein and are useful as anti-inflammatory agents for the treatment or prevention of diseases associated with an activation of the contact activation system (i.e., plasma kallikrein associated disorders). In general, a contact activation system disorder is a disease caused by activation of blood on artificial surfaces, including prosthetic valves or other implants, indwelling catheters, stents, cardiopulmonary bypass, hemodialysis, microorganism (e.g., bacteria, virus), or other procedures in which blood is exposed to an artificial surface that promotes contact activation, blood clots (i.e., diseases involving fibrin formation, platelet activation, and/or platelet aggregation). Contact activation can also occur on cell surfaces, cellular receptors or extracellular matrices, Diseases of the contact activation system also include systemic inflammatory response syndrome, sepsis, acute respiratory distress syndrome, hereditary angioedema or other inherited or acquired deficiencies of contact activation components or their inhibitors (plasma kallikrein, factor XIIa, high molecular weight kininogen, C1-esterase inhibitor). It may also include acute and chronic inflammations of joints, vessels, or other mammalian organs.

The effectiveness of compounds of the present invention as inhibitors of the coagulation factors XIa, VIIa, IXa, Xa, plasma kallikrein or thrombin, can be determined using a relevant purified serine protease, respectively, and an appropriate synthetic substrate. The rate of hydrolysis of the chromogenic or fluorogenic substrate by the relevant serine protease was measured both in the absence and presence of compounds of the present invention. Hydrolysis of the substrate resulted in the release of pNA (para nitroaniline), which was monitored spectrophotometrically by measuring the increase in absorbance at 405 nm, or the release of AMC (amino methylcoumarin), which was monitored spectrofluorometrically by measuring the increase in emission at 460 nm with excitation at 380 nm. A decrease in the rate of absorbance or fluorescence change in the presence of inhibitor is indicative of enzyme inhibition. Such methods are known to one skilled in the art. The results of this assay are expressed as the inhibitory constant, K_(i).

The Michaelis constant, K_(m), for substrate hydrolysis by each protease was determined at 25° C. using the method of Lineweaver and Burk. Values of K_(i) were determined by allowing the protease to react with the substrate in the presence of the inhibitor. Reactions were allowed to go for periods of 20-180 minutes (depending on the protease) and the velocities (rate of absorbance or fluorescence change versus time) were measured. The following relationships were used to calculate K_(i) values:

(v _(o) −v _(s))/v _(s) =I/(K _(i)(1+S/K _(m)))

for a competitive inhibitor with one binding site; or

v _(s) /v _(o) =A+((B−A)/1+((IC ₅₀/(I)^(n))))

and

K _(i) =IC ₅₀/(1+S/K _(m))

for a competitive inhibitor

where:

-   -   v_(o) is the velocity of the control in the absence of         inhibitor;     -   v_(s) is the velocity in the presence of inhibitor;     -   I is the concentration of inhibitor;     -   A is the minimum activity remaining (usually locked at zero);     -   B is the maximum activity remaining (usually locked at 1.0);     -   n is the Hill coefficient, a measure of the number and         cooperativity of potential inhibitor binding sites;     -   IC₅₀ is the concentration of inhibitor that produces 50%         inhibition under the assay conditions;     -   K_(i) is the dissociation constant of the enzyme: inhibitor         complex;     -   S is the concentration of substrate; and     -   K_(m) is the Michaelis constant for the substrate.

The effectiveness of compounds of the present invention as antithrombotic agents can be determined using relevant in vivo thrombosis models, including In Vivo Electrically-induced Carotid Artery Thrombosis Models and In Vivo Rabbit Arterio-venous Shunt Thrombosis Models.

In Vivo Electrically-induced Carotid Artery Thrombosis (ECAT) Model:

The rabbit ECAT model, described by Wong et al. (J Pharmacol Exp Ther 2000, 295, 212-218), can be used in this study. Male New Zealand White rabbits are anesthetized with ketamine (50 mg/kg+50 mg/kg/h IM) and xylazine (10 mg/kg+10 mg/kg/h IM). These anesthetics are supplemented as needed. An electromagnetic flow probe is placed on a segment of an isolated carotid artery to monitor blood flow. Test agents or vehicle will be given (i.v., i.p., s.c., or orally) prior to the initiation of thrombosis. Thrombus formation is induced by electrical stimulation of the carotid artery for 3 min at 4 mA using an external stainless-steel bipolar electrode. Carotid blood flow is measured continuously over a 90-min period to monitor thrombus-induced occlusion. Total carotid blood flow over 90 min is calculated by trapezoidal rule. Average carotid flow over 90 min is then determined by converting total carotid blood flow over 90 min to percent of total control carotid blood flow, which would result if control blood flow had been maintained continuously for 90 min. The ED₅₀ (dose that increased average carotid blood flow over 90 min to 50% of the control) of compounds are estimated by a nonlinear least square regression program using the Hill sigmoid E_(max) equation (DeltaGraph; SPSS Inc., Chicago, Ill.).

In Vivo Rabbit Arterio-Venous (AV) Shunt Thrombosis Model

The rabbit AV shunt model, described by Wong et al. (Wong, P. C. et al. J Pharmacol Exp Ther 2000, 292, 351-357), can be used in this study. Male New Zealand White rabbits are anesthetized with ketamine (50 mg/kg+50 mg/kg/h IM) and xylazine (10 mg/kg+10 mg/kg/h IM). These anesthetics are supplemented as needed. The femoral artery, jugular vein and femoral vein are isolated and catheterized. A saline-filled AV shunt device is connected between the femoral arterial and the femoral venous cannulae. The AV shunt device consists of an outer piece of tygon tubing (length=8 cm; internal diameter=7.9 mm) and an inner piece of tubing (length=2.5 cm; internal diameter=4.8 mm). The AV shunt also contains an 8-cm-long 2-0 silk thread (Ethicon, Somerville, N.J.). Blood flows from the femoral artery via the AV-shunt into the femoral vein. The exposure of flowing blood to a silk thread induces the formation of a significant thrombus. Forty minutes later, the shunt is disconnected and the silk thread covered with thrombus is weighed. Test agents or vehicle will be given (i.v., i.p., s.c., or orally) prior to the opening of the AV shunt. The percentage inhibition of thrombus formation is determined for each treatment group. The ID₅₀ values (dose which produces 50% inhibition of thrombus formation) are estimated by a nonlinear least square regression program using the Hill sigmoid E_(max) equation (DeltaGraph; SPSS Inc., Chicago, Ill.).

The anti-inflammatory effect of these compounds can be demonstrated in an Evans Blue dye extravasation assay using C1-esterase inhibitor deficient mice. In this model, mice are dosed with a compound of the present invention, Evans Blue is injected via the tail vein, and extravasation of the blue dye is determined by spectrophotometric means from tissue extracts.

Intravenously, the most preferred doses will range from about 0.001 to about 10 mg/kg/minute during a constant rate infusion. Compounds of this invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.

Compounds of this invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal routes, using transdermal skin patches. When administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.

The compounds are typically administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as pharmaceutical carriers) suitably selected with respect to the intended form of administration, that is, oral tablets, capsules, elixirs, syrups and the like, and consistent with conventional pharmaceutical practices.

For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic, pharmaceutically acceptable, inert carrier such as lactose, starch, sucrose, glucose, methyl callulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol and the like; for oral administration in liquid form, the oral drug components can be combined with any oral, non-toxic, pharmaceutically acceptable inert carrier such as ethanol, glycerol, water, and the like. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth, or sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes, and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum, and the like.

The compounds of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine, or phosphatidylcholines.

Compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethylaspartamidephenol, or polyethyleneoxide-polylysine substituted with palmitoyl residues. Furthermore, the compounds of the present invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyglycolic acid, copolymers of polylactic and polyglycolic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacylates, and crosslinked or amphipathic block copolymers of hydrogels.

Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 1 milligram to about 1000 milligrams of active ingredient per dosage unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.1-95% by weight based on the total weight of the composition.

Gelatin capsules may contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract.

Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.

In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol.

Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field.

Where the compounds of this invention are combined with other anticoagulant agents, for example, a daily dosage may be about 0.1 to 100 milligrams of the compound of the present invention and about 0.1 to 7.5 milligrams of the second anticoagulant, per kilogram of patient body weight. For a tablet dosage form, the compounds of this invention generally may be present in an amount of about 5 to 100 milligrams per dosage unit, and the second anti-coagulant in an amount of about 1 to 50 milligrams per dosage unit.

Where the compounds of the present invention are administered in combination with an anti-platelet agent, by way of general guidance, typically a daily dosage may be about 0.01 to 25 milligrams of the compound of the present invention and about 50 to 150 milligrams of the anti-platelet agent, preferably about 0.1 to 1 milligrams of the compound of the present invention and about 1 to 3 milligrams of antiplatelet agents, per kilogram of patient body weight.

Where the compounds of the present invention are administered in combination with thrombolytic agent, typically a daily dosage may be about 0.1 to 1 milligrams of the compound of the present invention, per kilogram of patient body weight and, in the case of the thrombolytic agents, the usual dosage of the thrombolyic agent when administered alone may be reduced by about 50-80% when administered with a compound of the present invention.

Where two or more of the foregoing second therapeutic agents are administered with the compound of the present invention, generally the amount of each component in a typical daily dosage and typical dosage form may be reduced relative to the usual dosage of the agent when administered alone, in view of the additive or synergistic effect of the therapeutic agents when administered in combination.

Particularly when provided as a single dosage unit, the potential exists for a chemical interaction between the combined active ingredients. For this reason, when the compound of the present invention and a second therapeutic agent are combined in a single dosage unit they are formulated such that although the active ingredients are combined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced). For example, one active ingredient may be enteric coated. By enteric coating one of the active ingredients, it is possible not only to minimize the contact between the combined active ingredients, but also, it is possible to control the release of one of these components in the gastrointestinal tract such that one of these components is not released in the stomach but rather is released in the intestines. One of the active ingredients may also be coated with a material that affects a sustained-release throughout the gastrointestinal tract and also serves to minimize physical contact between the combined active ingredients. Furthermore, the sustained-released component can be additionally enteric coated such that the release of this component occurs only in the intestine. Still another approach would involve the formulation of a combination product in which the one component is coated with a sustained and/or enteric release polymer, and the other component is also coated with a polymer such as a low viscosity grade of hydroxypropyl methylcellulose (HPMC) or other appropriate materials as known in the art, in order to further separate the active components. The polymer coating serves to form an additional barrier to interaction with the other component.

These as well as other ways of minimizing contact between the components of combination products of the present invention, whether administered in a single dosage form or administered in separate forms but at the same time by the same manner, will be readily apparent to those skilled in the art, once armed with the present disclosure.
